Thanks @Sreeju Nair for your prompt reply and apologies for delay on my end.
Let me explain the scenario in details...
We have Blazor WebAssembly core hosted app. The users are being authenticated using AAD. Here is the url of how the Blazor WASM authentication is set up:
https://learn.microsoft.com/en-us/aspnet/core/blazor/security/webassembly/hosted-with-azure-active-directory?view=aspnetcore-5.0
We will also have a public facing content website which should be accessible ONLY from the blazor server webapi. It does not matter who the user is. Only thing we need to be sure is, request is from WebApi. The files accessed by the WebApi will be presented to the client using "Static Files" architecture.
Everything else is working except the authentication of WebApi request to the content website using AAD. Any assistance in this regard will be highly appreciated.
